Specification forming part of Letters` Patent No. 199,665, dated January 29, 18782 application filed June 14, 1877.

To all whom it may concern:

Be it `known that I, HENRY ScHREnvER, of

l the city and county of Philadelphia, in the 'State of Pennsylvania, have invented a new and useful Improvement in Gar Starters, which improvement is fully set forth in the following specification and accompanying drawings, in which-L y Figure 1 is a plan view of that portion of a car to which my improvements are attached, showing the position of the moving parts before the car is started, the cover of the box Z being removed to show the arrangement of `the devices within the box. Fig. 2 is a verti- .sector-lever on one of the axles, is so constructed and arranged as to be automatically thrown out of connection therewith when the draftchain is drawn forward far enough to start the car, and in the backward movement of the chain in stopping the' car it i's held up at its front end by means of a stop confined to the bottom of the car, upon which it rests. The rear end is sustained by the front end of a weighted lever, which turns the pawl far enough, when the car is started, to throw it into connection with a ratchet-Wheel on one of the axles, and keep it in that position until it arrives at the disengaging-point, when it is again released automatically, as before stated. The rear end of the pawl and the connectin g end of the weighted lever are curved, as shown, to admit of a free and regular movement of the same. l

In the drawings Ihave represented so much of the front end of a car as is necessary to show my improvements. A is the front end of the bottom of a street-car; B, one of the axles, and C C its wheels. D is a sector-lever, which fits loosely on one end of the axle, between the contiguous wheel G and the ratchetheel E. G is a balancepawl hung on the `pin a., which projects from the side of the sec-v tor-lever D. The lever has grooves b and Zl in its segmental periphery, to receive chains, or ropes, or belts, or wires. The groove b receives the chain H, one end of which is fastened to the rear edge of the segment. The chain is passed from the lever around the pulleys I I in the casting c, and connects with the long end of the double sector J J, which is provided with `the groove d'to receive it, the lever working on the fulcrum-pin f, the lower end of the pin being fastened in the bottom A. "Ihe draft-chain L is held in the groove d in the periphery of the short sector J N is a weighted sector on the shaft 0, and P a chain, one end of which is fastened to the front edge of the sector-lever D, so as to come into the groove b in the forward movement of the lever. The other end of the chain lies in the groove b2 of the sector. l

The parts thus specified, with the exceptionof the above-named balance -pawl G, .are essentially the saine as shown in my car-starter patented June l2, .187 7, and therefore a more particular description thereof iis deemed unnecessary.

The rear and front ends of the balancepawl G are of equal weight, so that when the draft-chain is drawn out to its full extent, and the pawl is thereby disconnected from the tooth of the ratchet-wheel, it comes into its balanced position. When the car is stopped,

the weighted sector N automatically regainsl its backward position, and, by its connection above described with the sector-lever D, returns the latter into the like position, whereby the front end of the pawl Gis drawn onto the stop g connectedwith the lower side of the bottom A, the rear and curved end of the pawl resting on the front and curved end of the weighted lever Q hung on the pin h,whicl1 passes through the yoke R fastened to the bottom A; and `when the car is started, by

the drawing out Vof the draft-chain L, the double sector, acting through the chain H, gives a forward movement to the sector-lever D, and thereby the pawl Gr is moved forward, and the front end of the weighted lever Q bears the rear end of the pawl upward, so as l to connect its front end with the ratchetwheel E, for starting the car.

Sis the tongue, (shown clearly in Fig. 4,) and T is a casting, with which it is connected byl means of nthe joint-,pin j,`tl 1ecasting being. confined, by means of screws, or bolts, or other' joint-pin as the horses assume an angular poy sition with the car in turning curves.

Iclaim'as my inventionf The automatic bf lance-pawl G, in combina# tion with the sector-lever D, stop g, and Weighted lever Q, substantially in the manner and for the purpose set forth.
